The Universe is supposed to be the same everywhere and in all directions. So what’s that giant “cold spot” doing out there?
In a new study, scientists say that a particle that links to a fifth dimension can explain dark matter.
The “warped extra dimension” (WED) is a trademark of a popular physics model that was first introduced in 1999. This research, which was published in The European Physical Journal C, is the first to use the theory to explain the long-standing dark matter problem in particle physics. 
The idea of dark matter, which makes up most of the matter in the universe, is the basis for what we know about how the universe works. Dark matter is like a pinch-hitter that helps scientists figure out how gravity works. Without a “x factor” of dark matter, many things would dissolve or fall apart. Even so, dark matter doesn’t change the particles we can see and “feel,” so it must have other special qualities as well.

By using fluids to model inaccessible realms of the cosmos, Silke Weinfurtner is “looking for a deeper truth beyond one system.” But what can such experiments teach us?
To explain the cosmos without invoking cosmic inflation, physicist Neil Turok has proposed the existence of a mirror-image universe going backwards in time from the big bang. He tells us why the idea is so compelling.
Astrophotographers spotted what looks like a third tail flowing in front of, instead of behind, the glowing comet.
The green comet C/2022 E3 (ZTF), which last flew by Earth 50,000 years ago when Neanderthals still coexisted with humans, has been gradually making its way across the night sky over the last few days.
What’s more, as per a LiveScience report, this “anti-tail” appears to be flowing in the wrong direction and is, therefore, seemingly breaking the laws of physics.

AS technology advances rapidly, we’re getting closer to cracking space mysteries that once baffled scientists.
Some experts think we could solve mysteries like dark matter in the next decade.
We’ve rounded up some of the biggest space mysteries that scientists are hoping to solve in our life times.
What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics.
The universe has a number of bizarre properties that are difficult to understand with everyday experience. For example, the matter we know, consisting of atoms and molecules and other particles, apparently makes up only a small part of the energy density of the universe. The largest contribution, more than two-thirds, comes from “dark energy”—a hypothetical form of energy whose background physicists are still puzzling over.
Moreover, the universe is not only expanding steadily, but also doing so at an ever-faster pace. Both characteristics seem to be connected, because dark energy is also considered a driver of accelerated expansion. Moreover, it could reunite two powerful physical schools of thought: quantum field theory and the general theory of relativity developed by Albert Einstein. But there is a catch: calculations and observations have so far been far from matching. Now two researchers from Luxembourg have shown a way to solve this 100-year-old riddle in a paper published by Physical Review Letters.
Approximately 85% of the mass of our galaxy is comprised by dark matter, matter that does not emit, absorb or reflect light and thus cannot be directly observed. While several studies have hinted at or theorized about its composition, it remains one of the greatest unresolved physics problems.
Physicists all over the world have been conducting dark matter searches or trying to come up with new methods to directly observe different dark matter candidates. One hypothetical form of dark matter that has so far eluded detection is dark-photon dark matter.
An intriguing possibility is that dark matter is comprised of dark photons, which resemble photons (i.e., the particles that make up visible light), but interact with charges with feeble strength. These dark photons could theoretically have masses in the milli-electrovolt range, approximately a million times lighter than those of electrons and thus notoriously difficult to detect.
With so much death all around us, from the pandemic to the war in Ukraine to all the mass shootings, you might wonder what it all means. Queen Elizabeth gone. Betty White gone. And perhaps even a loved one of yours gone. They no longer exist, right? They are just memories, at least from a rational scientific perspective. But what if you’re wrong?
Dr. Caroline Soames-Watkins also believed that the world around her existed as a hard, cold reality ticking away like a clock. Death was a foregone conclusion—until she learned different. Caro, the protagonist of my new novel co-written with award-winning sci-fi author Nancy Kress, also thought she had the world figured out. Not her personal world, which has been upended by controversy, but how the physical world works and how her consciousness operates within it. Broke and without a job, she accepts a job offer from her great-uncle, a Nobel Prize-winning scientist who runs a research facility studying the space between biology and consciousness—between the self and what we assume is reality. They are on the verge of a humanity-altering discovery, which throws Caro into danger—love, loss, and death—that she could never have imagined possible.
Observer takes Caro on a mind-expanding journey to the very edge of science, challenging her to think about life and the power of the imagination in startling new ways. The ideas behind Observer are based on real science, starting with the famous two-slit experiments, in which the presence of an observer affects the path taken by a sub-atomic particle, and moves step-by-step into cutting-edge science about quantum entanglement, on-going experiments applying quantum-level physics to the macro-world, the multiverse, and the nature of time and consciousness itself.
